01 — The rail
Every profile, one window
Profile behavior in Dia was a pain. Now it's a pane. A single pane, pinned to your Dia window. Rename them, reorder them, tap to switch. The instance you land on takes the spot you left.
macOS · for the Dia browser
Your Arc profiles.
In One Window.
In Dia.
Like Spaces never left.
Dia gives every profile its own window and scatters them across your desktop. Diarc pins a switcher to your Dia window — tap a profile and it comes to the front. The calm, one-window focus Arc's Spaces had, grafted onto the browser you moved to.
02 — Hands off
We don't touch Dia
A separate app. No injection, no SIP disable, nothing to void. Dia has no idea we exist, just like how BCNY made Arc fans feel.
03 — Native
A real Mac app
Tiny footprint, SF-native, and it updates itself. Not an extension in a trenchcoat... Diarc is more of a "smoking jacket" kind of app.
